Hi. This forum is great, I have been reading absolutely everything I can and I think I have done this all correctly, but I'm not confident and would appreciate any input. I am adding a second bathroom to the second story of my 70's build house and attempting to tie into the existing stack.
Existing in black, new drain in blue, new vent in green. Tie-in at the existing stack is a 3x3x3x1-1/2" (the 3" and 1-1/2" are offset 90 degrees) hub, the horizontal branch will be a new wye, with the branch on the wye-side (existing WC on the "straight-through" side).
THANKS!
